The Super Ceph View Tab gives the ability to construct and view an enhanced version of a cephalometric radiograph, take measurements, and utilize several image enhancement features, all of which dramatically increases its diagnostic value.
Super Ceph: Toolbar
Shown below is the Toolbar and tools that are loaded with the Super Ceph View Tab:
Reset View: Resets the rendering window to the original view.
Left View: Automatically orients the volume so the patient is facing left sagittal.
Front View: Automatically orients the volume so that the patient is facing the front.
Right View: Automatically orients the volume so the patient is facing right sagittal.
Distance Measurement: After selecting this tool, click two points to mark the desired distance.
A number in millimeters will automatically display.
Angle Measurement: After selecting this tool, click the first point, then click the vertex, then click the last point to create an angle. A number in degrees will automatically display.
Grid: Toggles between two different grid layouts for use in the all of the section frames allowing quick assessment of measurements and spatial location.
Information Display: Displays or hides case information embedded in the data.
Change Layout: Toggles between different Super Ceph layouts. “Set Orientation” must be enabled to allow toggling between layouts.
Warning: Any measurement that is incorrect can lead to surgical complications if diagnosis, treatment plans and/or actual treatment is based on the incorrect measurements. It is critical for the end user to learn how to perform measurements correctly and employ proper usage of all measurement tools. Measurement accuracy depends on the image data and the hardware scanner that generated the image data. The measurement cannot be more precise than the resolution of the image. Software reports the value based on user-picked points.
Due to the nature of medical imaging, the boundary is not always well defined. The apparent boundary depends on the current brightness and contrast setting. The boundary may shift as the user makes adjustments to brightness and contrast. The user must understand the limitation of the measurement value before applying to the patient. If you notice any inconsistencies or software problems with measurements, or have further questions or concerns about using measurement tools correctly, please contact us at (408) 885-1474 or email us at [email protected]
Super Ceph: Control Panel
Create Ceph
• The Create Ceph button should only be clicked after the orientation of the patient’s volumetric image is adjusted in the rendering window.
• The “Set Orientation” box will reset the orientation if a ceph was created incorrectly. Once the image is orientated correctly, press the Create Ceph button again.
Layout:
• “Screen” layout is optimized for viewing the image on the computer screen. “Print Out” layout is optimized for printing the image on paper. With Print Out layout, what you see on screen will be what you get on the paper in life-size. First, capture to Gallery, then print from Gallery to ensure the image is life size.
Traditional Gray Scale Ceph
• Brightness and Contrast can be adjusted to enhance your image.
• The “Enhanced” box can be left-clicked on or off to sharpen and enhance the quality of the image.
• Range Setup allows you to select which side of the patient’s head the ceph will be created from.
Thickness allows you to control how thick the range is.
• When you change the Range Setup, you must recreate the ceph image using the Create Ceph button.
• Sharpening Filter: Applies the selected sharpening filter from the drop-down menu to the 2D slice renderers.
Volume Ceph
• Increase the Opacity slider bar to superimpose the volume rendering onto the generated ceph.
• Various enhanced views of the ceph can be added;
each has different advantages:
• Bone highlights hard-tissue landmarks
• Soft+Bone emphasizes the soft-tissue on the ceph Opacity, Brightness, and Contrast can all be adjusted for image enhancement.
• Inverse switches the background to white (Gray Scale coloring switches black/white).
• Range Setup allows you to select which side of the patient’s head the ceph will be created from.
• Projection allows you to switch from parallel views of the cephalometric images to perspective views which resemble the magnification found in traditional cephalometric radiographs.
Super Ceph: Rendering Window
This window is where the volumetric image of the patient is orientated to create a ceph and is where the ceph will be viewed after creating it.
Before clicking on the Create Ceph button in the Control Panel, the patient’s volumetric image must be correctly orientated. The easiest way to do this is to line up the left and right angles of the mandible. If the ceph is created with an improper orientation, it can be adjusted using the “Set Orientation” box in the Control Panel.
Please refer to Image Navigation (pg. 30) for information about controlling and adjusting these images.
Super Ceph: Change Layout
The default rendering layout for the Super Ceph tab is a five-volume view with a shared rendering preset.
Each volume will initially be oriented at a different angle from the other volumes but can be rotated, panned, zoomed, or free-moved to a new orientation independent of the other volumes.
The user can switch to the Create Ceph layout by clicking the Change Layout button, . Switching back to the five-volume layout can be done by clicking once more on the Change Layout button when “Set Orientation” is enabled. (This will delete your current ceph, so it is recommended that you capture the ceph to the Gallery before selecting “Set Orientation.”)
